[Bug 417433] Re: Maxima crashes on solve, finding determinants, and other operations

[Ilya Barygin]

I've got a workaround. Before starting maxima, run

sudo sysctl kernel.randomize_va_space=0

This turns off a security-hardening setting (see
https://wiki.ubuntu.com/Security/Features#ASLR) which gcl doesn't play
nice with. You may want to reset it after you're done with maxima, for
me the default value is 2, you can find it out by running "sysctl
kernel.randomize_va_space" prior to turning off.

So there's an underlying problem with gcl which FTBFS for me because of
this problem. I think we should find a way to fix gcl first, then
rebuild maxima against fixed gcl.
